I was trying to use a rule parameter and can't call another rule with that
parameter when I use +. An example will make more sense.
test [bool wtf] returns [int n]:
{$wtf}?=>'wtf' test2[$wtf]+; // attribute is not a token, parameter,
or return value: wtf
test [bool wtf] returns [int n]:
{$wtf}?=>'wtf' test2[$wtf]; // works fine
test [bool wtf] returns [int n]:
{$wtf}?=>'wtf' test2[false]+; // works fine as well
test2 [bool wtf2]:
{$wtf2}?=>'foobar';
If I take the gated semantic predicate out of test2, then all the above
work.
test2 [bool wtf2]:
'foobar'; // works for all the above
What did I miss?
Thanks
